## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dns-cname-imap-subdomain-de510a78
```

Example prompt: Can you check if imap.rallylive.ca has a CNAME record set up and tell me what it points to and its TTL?

## When to prefer this

Use this endpoint when you need a fast, single-purpose existence and resolution check for the imap.<domain> CNAME specifically, without enumerating other subdomains. Ideal for email infrastructure validation, onboarding checks, and diagnosing IMAP connectivity issues. Prefer this over general DNS tools when you only care about the imap host and want a pay-per-lookup model with Cloudflare DoH reliability.

## Known failure modes

- Domain does not exist — no records returned
- imap subdomain has no CNAME record (may have A/AAAA instead)
- Malformed domain input causing query failure
- Cloudflare DoH upstream timeout or error
- Rate limiting or payment failure resulting in no response

## How this service works

CNAME record of imap.<domain>: looks up the imap host under the domain you give (CNAME via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like imap without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the imap.<domain> CNAME record exists, the record's target hostname, TTL value, and any associated DNS record data retrieved via Cloudflare DoH. If the record does not exist, the response indicates absence.
